Particle Discharge (PD) Tester

The PDSurveyor™ family has been designed to carry out Partial Discharge detection by all operational staff entering the substation or facility. 'Look-see' PD tests can be made quickly and easily to scan large numbers of cables and plant items for PD activity as a prelude to using diagnostic PD test and/or monitoring technology.

With the recent addition of 3x new handheld PD screening units to our standard PDSurveyor™ offering, HVPD can offer solutions for testing all types of MV plant in the voltage range from 3.3 kV to 45 kV, as follows:

  • PDSurveyor™- suitable for cables and switchgear
  • PDS Air™- suitable for indoor and outdoor switchyards
  • PDS Rogowski™- suitable for machines with permanently installed Rogowski Coil sensors
  • Filter

Product Overview *New* - The PDS Air™ partial discharge surveying tool from HVPD represents the very latest in handheld PD test technology. Incorporating a digital TEV-dB display and external airborne acoustic probes, the test unit provides the 'first-line of defence' for the early detection of PD activity in MV cables and plant from 3.3 kV to 45 kV. Rapid, 'look-see' insulation condition testing is possible through the unique combination of three PD measurement technologies: HFCT, TEV and Airborne Acoustic. The PDS Air™ handheld test unit meets the requirements of both utility and industrial MV plant owners for a simple, portable, and easy-to-use handheld PD screening device for use by all operational staff in the substation. The unit is recommended for use in Phase 1 of the HVPD 4-Phase PD Test and Monitoring Solution which requires PD pre-screening of 100% of the network. Benefits include Digital TEV sensor measurement with numerical LED display. The only handheld PD test unit in the market to combine 3x PD sensor technologies (TEV, Acoustic and HFCT) in one device. Measurement of PD in metal-clad switchgear/plant with airborne acoustic sensors and accurate digital...

PDSurveyor™ Product Overview The PDSurveyor™ is HVPD's original handheld PD surveying tool. It is the 'first-line of defence' for the detection of partial discharge activity in On-line medium voltage (MV) power cables and plant in the voltage range 3.3 kV to 45 kV. The unit enables the user to carry out rapid (10 - 20 seconds per plant item), 'look-see' insulation condition testing through a unique combination of measurement technology, incorporating three types of PD sensor: HFCT, TEV and Airborne Acoustic. The PDSurveyor™ has been designed by HVPD to meet the specific requests from both utility and industrial MV plant owners for a simple, portable and easy-to-use PD test device which can be used by all operational staff in MV substations. The PDSurveyor™ is the most flexible handheld PD screening device on the market as it contains three built-in PD sensors to enable the unit to be used to detect partial discharge activity in MV plant including metal-clad switchgear and power cables. Alternative versions of the unit are now available for specialist purposes, including the testing of rotating machines; see the PDSurveyor™ Family page for more info. The primary...
